[SOLVED]Useless boot partition(forgot to mount it during installation)

I recently figured out (Arch installed a week ago) that my /boot is on /dev/sda2 while I dedicated my /dev/sda1 to it. It's probably because I forgot to mount it during installation. Could anyone tell me how I can have my boot-related stuff (including kernels, I use stock,lts and pf) moved to this partition? I use grub2. All answers are appreciated.

Re: [SOLVED]Useless boot partition(forgot to mount it during installation)

Just mount the new partition to /mnt and copy over the contents of /boot to there and then change your fstab & grub.cfg (either manually or using `grub-mkconfig` after you have re-mounted /boot).

Alternatively, you could re-mount /boot using:

# umount -R /boot
# mount /dev/sda1 /boot

Then re-install the linux package & GRUB, re-configure grub.cfg and modify /etc/fstab

Re: [SOLVED]Useless boot partition(forgot to mount it during installation)

Mount that partition somewhere. Copy /boot to it. Modify /etc/fstab to mount that partition on boot.
Update/reconfigure/reinstall grub configs I don't know much about grub... sorry).
Test if it works.
Finally/optionally cleanup the old boot folder on your root partition if.

Edit: too slow...;)

I put at button on it. Yes. I wish to press it, but I'm not sure what will happen if I do.  (Gune | Titan A.E.)

Re: [SOLVED]Useless boot partition(forgot to mount it during installation)

Thanks!

[plantroon@plantroon-ga-m56s-s3 ~]$ sudo mount /dev/sda1 /boot
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.
[plantroon@plantroon-ga-m56s-s3 ~]$

What FS should I use for that partition ? Ext4 works fine ?

Also, I don't really know what /boot should look like in fstab

Re: [SOLVED]Useless boot partition(forgot to mount it during installation)

Looks like you also forgot to create a filesystem on /dev/sda1. Ext4 works fine, yes.
Fstab entry.

/dev/sda1 /boot ext4 defaults 0 2

Ext4 should do the job, although ext2, ext3 or fat will also do just fine.

The arch wiki has a page dedicated to the fstab, so please look there.

Now its stuck in a reboot loop right before grub should be displayed.

Two methods were proposed -- which one did you use and which commands did you enter?

Post the content of your /etc/fstab

Have you reinstalled and reconfigured grub as dice already mentioned? See the GRUB wiki page.

Re: [SOLVED]Useless boot partition(forgot to mount it during installation)

cat /etc/fstab
# 
# /etc/fstab: static file system information
#
# <file system>	<dir>	<type>	<options>	<dump>	<pass>
# /dev/sda1
#UUID=9b5cec27-929f-461f-8481-4a34413315eb	/boot 		ext4 		defaults 			0 2
# /dev/sda2
UUID=4525db02-78f1-4492-9d0c-2bee53fd5e6a	/         	ext4      	rw,relatime,data=ordered	0 1
# /dev/sdb1
UUID=8b882a84-ff40-4275-a53d-274a74da4d96	/home     	ext4      	rw,relatime,data=ordered	0 2
# /dev/sda3
UUID=865c0e95-e374-4a5d-a859-d57c2cb3df3b 	none 	swap 			defaults,pri=10  		0 0

My problem was that I completely confused bios boot partition with /boot. I literally tried to merge them I found on google that some other guy did the same thing. While I have a working system right now, is there any way I could rename /dev/sda2 to be sda3 and sda3 to sda4 ? As you can see I use UUIDs in fstab anyways.

EDIT/UPDATE: sort (s) in gdisk did the thing

Re: [SOLVED]Useless boot partition(forgot to mount it during installation)

Quick question, why is your /boot commented out?

Re: [SOLVED]Useless boot partition(forgot to mount it during installation)

Quick question, why is your /boot commented out?

Because I had to use the /boot directory on my root drive to boot into the system. Only later then I managed to realign the partition table and just a while ago I got it all working as I want it
Thanks for the help everyone!
